Stopwords(Elasticsearch7.14+ fscrawler2.7)

how to configure stopwords. I am in fscrawler2.7 and Elasticsearch7.14

Welcome!

You need to define your own analyzer as explained in Elasticsearch settings — FSCrawler 2.7 documentation

I'd recommend doing it manually with (quote from docs):

Note that if you want to push manually the mapping to elasticsearch you can use the classic REST calls:

# Create index (don't forget to add the fscrawler_path analyzer)
PUT docs
{
  // Same index settings as previously seen
}

You can configure the stopword of the language analyzer you want to use. See Language analyzers | Elasticsearch Guide [7.14] | Elastic

Or for example:

PUT /docs

  "settings": {
    "number_of_shards": 1,
    "index.mapping.total_fields.limit": 2000,
    "analysis": {

Hello,
i'm beginner in elasticsearch and fscrawler, i can't configure stopwords i use elasticsearch 7.14 and fscrawler2.7, can you help me please?

I think that's what I did already.

What is the problem?

the problem is
{
"error" : {
"root_cause" : [
{
"type" : "illegal_argument_exception",
"reason" : "The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true."
}
],
"type" : "illegal_argument_exception",
"reason" : "The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true."
},
"status" : 400
}

Could you try:
